Casa Grande, AZ Animal Ordinances: Breed Restrictions (2026)

Casa Grande does not maintain a list of restricted dog breeds. Instead, Casa Grande Municipal Code § 6.08.090.A defines a "vicious animal" by conduct or by formal declaration: any animal of the order carnivora that has a propensity to bite human beings or other animals without provocation, that kills another animal without provocation, or that has been so declared after a hearing before a justice of the peace or a city magistrate. Subsection B makes it unlawful to let a dangerous or vicious animal run at large anywhere in the city, and requires the animal control officer to impound it immediately once identified.

Subsection C directs that vicious animals be destroyed in a manner provided by law, and § 6.08.100 separately authorizes the animal control officer to kill any dangerous animal of any kind, vicious-designated or not, when necessary to protect a person or property. Because § 6.08.090 sits within Chapter 6.08, a violation, such as an owner letting a declared vicious animal run loose, is punishable as a Class 2 misdemeanor under the chapter's jurisdiction clause in § 6.08.020, heard in the Casa Grande City Court. The magistrate hearing referenced in subsection A gives an owner a due-process step before an animal is formally labeled vicious, distinguishing Casa Grande's conduct-based approach from breed-specific ordinances used elsewhere; any breed of dog, cat, or other carnivore can be declared vicious here based on its actual behavior or a magistrate's finding.
